It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

C) the number of the pricipal energy level containing the outer electrons increases
Answer:
Sodium chloride (Table Salt)
Explanation:
When two or more elements combine with or without the application of heat, a compound is formed. Any compound in which the elements have a complete gain and loss of electron is termed as ionic compound.
Ionic compounds have the excellent property of dissolving in water. They form ions, both positively charged and negatively charged, which conduct electricity in aqueous medium and therefore can be called as electrolytes.
Sodium chloride (Table Salt) is a common example of ionic compound. It dissolves in water. It is an electrolyte and it is an excellent conductor of electricity. So, the best choice would be Sodium chloride.
